hi i'm steven and i have question???
what is answer to
2 x + y = 1
y = -¹/₃ x - 4
this is secondary level
please send answer by today

thank you

Hi Steven,

From the second equation you know that the value of y is minus one third of the value of x minus 4. Take this knowledge of y and substitute it into the first equation. That is

2 x + y = 1

so

2 x - ¹/₃ x - 4 = 1

Now you need to solve for x. I would first multiply both sides by 3 to eliminate the fraction.
